Appiication filed June 3, 1908.

To all whom it may concern:

Be it known that I, ROLAND O. BINGHAM, a citizen of the United States,residing at Mount Gilead, in the county of Morrow and State of Ohio,have invented certain new and useful improvements in Pumps, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to improvements in pumps for wells, cisterns andthe like.

The object of the invention is to provide a pump of this character whichmay be quickly and easily removed from the well for the pur-' pose ofrepairing its valves or other reasons, without removing the stand-pipeor other fixtures in the lower portion of the well.

With the above and other objects in View, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a vertical sectional viewthrough my improved pump; and Fig. 2 is a detail horizontal sectiontaken on the plane indicated by the line 2-2 in Fig. 1.

1n the drawings 1 denotes a portion of a well, cistern or the like, and2 its cover in which my improved ump is mounted. The pump comprises a cyinder 3 which is removably mounted in a casing 4 which has a standpipe 5depending from its lower end and its upper end suitably connected to thecover 2. As shown, the casing 4 is cylindrical and of slightly greaterinternal diameter than the pum cylinder 3, and at its upper end is annnu ar flange 6 to rest upon and to be bolted or otherwise secured tothe top of the well cover 2. The lower end of the cylindrical casing 4is closed by a removable screw cap or head 7 into which the water pipeor standpipe 5 is threaded. Adjacent to the upper end of the casing 4 isa vent aperture or air hole 8 and adjacent to its lower end is a drainhole 9.

The pump 3 which may be of any suitable form and construction is adaptedto have its lower end rest upon a gasket 10 arranged in the bottom ofthe casing 4- and at or adjacent to its upper end is an annular flangel1 adapted to rest upon the flange or top 6 of the casing and to bedetachably secured thereto by bolts or similar fastenings 12. Asillustrated, the pump 3 has a cylindrical body Specification of LettersPatent.

composed of upper and lower sections having a detachable screw threadedconnection 13, the lower section having at its bottom a check valve 14.Another check valve 15 is arranged in the plunger or piston 16 carryinga sucker rod 17, which latter may be actuated by any suitable means. Inthe pump cylinder 3 may be provided a small drain hole 18.

From the foregoing it will be seen that by removably mounting the bodyof the pump in the casing 4 which has the stand-pipe depending from itslower end and means at its upper end for supporting it from the cover ofthe well, the pump may be readily removed so that it may be cleaned, itsvalves repaired, etc. By mounting the pump in this manner the necessityof removing the stand-pipe or other pipes and connections in the lowerportion of the well is obviated and the pump may be more quickly andeasily cleaned and repaired.

Having thus described my invention what I claim is:

1. The combination of a casing having an air vent opening adjacent toits top and a drain opening adjacent to its bottom, a stand-pipedepending from said casing, means at the top of the casing for securingthe same to a well cover or the like, and a pump cylinder removablyarranged in the casing and of less diameter than the latter, saidcylinder being formed with a drain opening.

2. The combination with the cover of a well or the like having anopening, of a casing arranged in said opening and provided at its topwith an apertured flange 6 to rest upon the cover, the body portion ofsaid casing being cylindrical and having its lower end internallythreaded and its side portion formed with the air vent opening 8 and thedrain opening 9, a removable screw cap engaged with the threaded lowerend of the casing, a stand-pipe depending from said cap, the washer 10arranged in the casing upon the upper face of said cap, a pump cylinderof less diameter than the casing removably arranged therein and composedof upper and lower detachable sections having a screw threadedengagement with each other, the lower section being adapted to rest uponsaid washer and containing a check valve and the upper section beingformed with the drain Q meme opening 18 and'the 'apertured flange 11toirest, In testimony whereof I hereunto affix my upon thefiange fiofthe casing and ltogh'ave signature inuthepresence-of two Witnesses.
